Detailed
What is Feed Grade Magnesium Sulphate Heptahydrate?
Feed Grade Magnesium Sulphate Heptahydrate (MgSO₄·7H₂O) is a high-purity, hydrated form of magnesium sulfate specifically manufactured for use in animal feed. It serves as an essential dietary supplement to provide magnesium and sulfur, two vital nutrients required for proper growth and metabolism in livestock, poultry, and aquaculture.
Core Features
1. High Purity & Safety
-Specially refined to meet feed-grade standards, ensuring low levels of heavy metals (e.g., lead, arsenic) and contaminants.
-Safe for livestock, poultry, and aquaculture without toxic side effects.
2. Essential Nutrient Supply
-Magnesium (~9.7%): Critical for enzyme activation, neuromuscular function, and bone development.
-Sulfur (~12%): Vital for synthesizing sulfur-containing amino acids (e.g., methionine, cysteine) and proteins.
3. Excellent Solubility & Bioavailability
-Rapidly dissolves in water, ensuring efficient absorption in the animal’s digestive tract.
-Enhances nutrient utilization compared to inorganic magnesium sources.
4. Multi-Species Compatibility
-Suitable for ruminants (cattle, sheep), monogastrics (pigs, poultry), and aquatic animals (fish, shrimp).
-Prevents deficiencies like grass tetany in cattle or poor eggshell quality in poultry.

Multi-Species Nutrient Optimization
Poultry & Livestock Applications:
Prevents heat stress by balancing electrolytes in poultry/cattle
Enhances vitamin absorption (+12% vitamin D₃ utilization)
Strengthens eggshell quality & reduces bone disorders in layers
Aquaculture Solutions:
Aquaculture Solutions:
Critical for shell formation in shrimp/crabs (reduces molting mortality by 18%)
Boosts gill function and disease resistance in fish with vitamin C synergy
Technical Advantages:
• Rapid solubility (>98% in 20°C water) for uniform feed mixing
• Adjustable granulation: 20-80 mesh (anti-caking optimized)

Application
1.Ruminants (Cattle, Sheep)
-Prevention of Grass Tetany:
During rapid spring grass growth, supplementing magnesium (recommended dietary addition of 0.5-1%) effectively prevents hypomagnesemia-induced convulsions and sudden death.
-Improved Lactation Performance:
Adding to dairy cow feed increases milk fat content (recommended dosage: 15-30g per head daily).
2.Monogastric Animals (Pigs, Poultry)
-Swine Management:
Growth Performance: Adding 0.3-0.5% to fattening pig diets enhances protein synthesis.
Stress Relief: Supplement 0.1% aqueous solution in drinking water during transport or regrouping.
-Poultry Production:
Layers: Adding 0.2-0.4% improves eggshell strength and reduces breakage.
Broilers: Enhances feed conversion ratio (recommended dosage: 0.15-0.3%).
3.Fish (e.g., Carp, Tilapia)
3.Fish (e.g., Carp, Tilapia)
-Osmoregulation: Adding 0.1-0.2% to freshwater feed maintains electrolyte balance.
-Anti-Stress: Apply 5-10ppm via water 3 days before harvesting/transport to reduce mortality.
4.Crustaceans (Shrimp, Crabs)
-Molting Support: Use with calcium sources (e.g., calcium phosphate) at a Mg:Ca ratio of 1:2 to promote shell hardening.
-Water Quality Improvement: Regular application (10-15ppm) prevents soft-shell syndrome.
5.Specialty Animal Applications
-Pet Feed: Adding 0.05-0.1% to dog/cat food helps prevent urinary stones (ensure adequate water intake).
-Fur Animals (Rabbits, Mink): Adding 0.2-0.4% to breeding females' diets reduces postpartum convulsions.

FAQ
How does it differ from industrial/agricultural grades?
Feed grade has:
-Strict heavy metal limits (e.g., <10ppm arsenic, <30ppm lead)
-Higher purity (≥99%) for animal safety
-Controlled particle size for uniform feed mixing
What's the shelf life and storage advice?
-Shelf life: 2 years in original packaging
-Storage: Keep in sealed containers at <30°C, <60% humidity
-Warning: Caking may occur if exposed to moisture (can be crushed before use)
Precautions for aquatic supplementation?
Key points:
-Freshwater farming: prioritize feed addition
-Marine farming: must calculate background water values
-Avoid strong sunlight when applying
-Better results when used with aeration equipment
